Oecumenius, on 1Pet 5:8

“Be sober and watch: because your adversary the devil, as a roaring lion, goeth about seeking whom he may devour.”

“"Be sober-minded; be watchful." On those who are spiritually asleep (this, however, is to aspire to vain things) and from this, the watchfulness of souls is weighed down, the evil and most savage beast of despair is accustomed to leap upon them. Therefore, Christ's disciple, strengthening us (Matt. 13:24), exhorts us to always be vigilant and to watch over him who sows tares, lest in any way, while we are asleep, or living carelessly and sluggishly, he secretly sows wicked thoughts and drives us away from true life. For the Devil does not cease, Peter says, prowls around like a roaring lion, seeking someone to devour; to whom you also resist with firm strength of mind. Concerning such sharp snares and the precise deceit of him against us, the holy Justin Martyr also brings forth the case, stating that the Devil did not clearly know the power of his punishment before the coming of the Lord, when the divine prophets had announced it mysteriously: just as Isaiah (14:4), under the persona of the Assyrian, tragically narrates the entire representation of the Devil. But when the Lord had come and had openly said that the eternal fire is reserved and prepared for the Devil and his angels (Matt. 25:41), upon hearing this, he does not cease to lie in wait for the faithful, wanting to have many companions in his defection, lest he be ashamed to cling to this alone, applauding himself with this cold and envious consolation.”
